自称携带手榴弹的一对父子劫持了哥伦比亚一架客机，并当客机在首都波哥大紧急迫降四个多小时以后释放了机上全部乘客。请看报道：

A father in a wheelchair and his son used two grenades to hijack¹ an airliner² Monday, but peacefully surrendered five hours later after allowing the crew and passengers, including one American, to leave the plane, authorities said.

The freed hostages told reporters the elder hijacker³ said he needed the wheelchair after being hit by a police bullet during a drug raid some 14 years ago and had unsuccessfully sought compensation.

Sen. Carlos Moreno, who helped negotiate the standoff, said a $230,000 check was handed to the hijacker, but that the government would not honor it.

standoff在文中是a situation in which agreement in an argument does not seem possible"僵局"的意思。例如：Diplomats said yesterday that the renewed standoff represented a setback⁵ for the Helsinki process.（外交官们昨天说重新开始的僵局表明了赫尔辛基进程的倒退。）
